• Always use a sharp diamond blade.
• Diamond blades can become blunt if you use an
incorrect feeding pressure or when you cut materials
such as hard reinforced concrete. If you use a blunt
diamond blade it becomes too hot, which can cause
the diamond segments to come loose.
To sharpen the cutting blade
Note: For the best cutting results, use a sharp cutting
blade.
• To sharpen the cutting blade, cut into soft material,
such as sandstone or brick.
Diamond blades for wet cutting
• Diamond blades for wet cutting must be used with
water.
• Water decreases the temperature of the cutting
blade, increases its service life and decreases dust
during operation.
• When wet cutting, collect the waste water safely.
Diamond blades for dry cutting
• For diamond blades for dry cutting it is necessary to
have a sufficient airflow around the cutting blade to
decrease the temperature. Because of this, diamond
blades for dry cutting are recommended only for
intermittent operation. After some seconds of
operation, it is necessary to let the diamond blade
rotate freely, away from the cut. This lets the airflow
around the blade decrease the temperature of the
diamond blade.
Diamond blade - side clearance
WARNING: Certain cutting situations or poor
blades can suffer excessive wear on the
side of the segments. Make sure the
diamond segment (T1) is wider than the
blade (T2). This is to prevent pinching in the
cutting slot and kickback. Refer to
on page 58 .

To examine the spindle shaft and the
flange washers
Examine the spindle shaft and the flange washers when
Kickback
you replace the cutting blade.
1. Make sure that the threads on the spindle shaft are
not damaged. Replace damaged parts.
T1
CAUTION: Some cutting situations and worn
blades may cause increased wear on the
side of the segments. Replace the blade
before it is worn out.
CAUTION: Use only Husqvarna flange
washers with a minimum diameter of 105
mm/4.1 in.
WARNING: Do not use defective, worn or
dirty flange washers. Use only flange
washers of the same dimension. Incorrect
flange washers can cause the cutting blade
to become damaged or come loose.
